'This'invention relates to a'machinelrfor eiect-` ingoperations in akitchen, such asY kneading, r'nixing, grinding and thelike, al1-exampleof `such type of machine being foundin Uf.

The portion of the bolt 22 which projects beyond the slot 23 is threadedas shown in Fig. 2, and this threaded portion of the bolt 22 adjustablyreceives a nut 26, preferably formed as a cap nut and which constitutesthe supporting foot I9 while at the same time serving as a locking meansfor the arm I5. To facilitate the manipulation of the nut 26, it ispreferably knurled or milled as indicated at 2|. The outer end of thenut is preferably provided with a sole piece 21 or the like, of rubberor other similar soft material which is held in position by means of ascrew 29 and interposed washer 28.

When the nut 26 is to serve as a locking device for the arm l5, said nutand an interposed friction washer 30, cooperate with a curved face 3|arranged on the pillar or standard l l outside of and adjacent to theslot 23. Between the outer end of the bolt 22 and the 'oase of the cap`nut 26 is provided a compression spring 32 which prevents the nut frombeing loosened unintentionally.

From the foregoing, the operation of the described structure will bereadily understood. By loosening the nut 25, the arm l may be swung toany desired angular position within the limits of the slot 23, such as,for example, to the position shown in dotted lines in Fig. 2, and thearm is then maintained in such position by tightening the nut 26. Byagain loosening the nut, the torsional spring 2li will operate to returnthe arm to its end position, as shown in full lines in Fig. 2, in whichposition the nut 26 will be positioned to serve as the supporting footI9 for the machine, should it be desired to place the machine in theoperative position of Fig. 1.

What I claim is:

l. In combination with a machine of the character described having abase whose bottom and a side thereof are provided with supporting feetto enable the machine to be supported in either position of the base, ofa standard projecting from such base, an arm pivotally mounted on saidstandard, and means for securing said arm in any selected position ofits pivotal movement, said means including an element serving as asupporting foot for the machine when the latter is positioned to besupported by the feet at the side of the base.

2.1In combination with a machine of the character described having abase adapted to be supported on its bottom or on a side thereof providedwith supporting feet, of a standard projecting from such base, an armpivotally mounted on said standard and having a limited pivotal movementwith respect to the latter, and means for securing said arm at anyselected point in its pivotal movement, said means including a nrst partprojecting radially from said standard and a second part coactingtherewith which is frictionally operative against a portion of saidstandard, said second part including means serving as a supporting footfor the machine when the latter is positioned to be supported by thefeet at the side of the base.

3. In a machine of the character described, a base, a standard arisingtherefrom, an arm having a restricted pivotal movement in said standard,means for urging the arm in one direction, means for locking the arm atany selected point in its pivotal movement, said locking means includinga threaded element extending radially from a part of the arm andprojecting out of the standard, and a nut adjustable on said threadedelement and frictionally operative against a part of the standard, saidnut having a portion serving as a supporting foot for the machine whenthe machine is arranged in one of its operative positions.

4. In a machine of the character described, a base, a standard arisingtherefrom, an arm pivotally mounted in said standard, a projectionextending radially from a part of the arm, the standard having a slot inwhich said projection is disposed and which limits the movement of theprojection and the swing of the arm, a member adjustable on theprojection and adapted to serve as a supporting foot for the machinewhen the machine is disposed in an operative position, and spring meanstending to swing the arm to a position wherein said member becomesoperative as a supporting foot.

5. In a machine of the character described, a base adapted for supportupon either its bottom or its side, a standard arising from the base, aswinging arm mounted in said standard, the standard having an arcuateslot provided in its wall, a bolt projecting radially from a part of theswinging arm and guided in the slot and limited in its movement by theends of the slot, a nut adjustable on the end portion of the bolt on theoutside of the standard, the standard presenting a curved surfaceagainst which the nut is frictionally operative to thereby hold the boltat any selected point in its travel in the slot, the nut being arrangedto serve as a supporting foot at a time when the base is resting uponits side.

6. In a machine as provided for in claim 5, wherein the outer surface ofthe nut is provided with a soft sole member; wherein spring means isprovided for normally positioning the arm in a position wherein the nutcan act as a supporting foot, and wherein xed supporting feet areprovided on the side of the base for cooperation with the nut insupporting the machine on its side.

7. In combination with a machine of the character described having abase whose bottom and a side thereof are provided with supporting feetto enable the machine to be supported in either position of the base, ofa member projecting from such base, an arm having a portion angularlymovable in said member between definite limits, a locking devicearranged to hold said arm in any desired position in its range ofangular movement, said locking device including an element disposedexteriorly of said member which is adapted to serve as a supporting footin the side position of the base when said arm is disposed at one limitof its angular movement.

8. In combination with a machine of the character described having abase whose bottom and a side thereof are provided with supporting feetto enable the machine to be supported in either position of the base, ofstructure comprising a plurality of parts including a member projectingfrom the base and an arm carried at the end of such member and angularlymovable thereon, and means removed from the base which is fixed to apart of said structure other than said projecting member and serves as asupporting foot for the machine when the latter is positioned to besupported by the feet at the side of the base.

9. In combination with a machine cf the character described having abase whose bottom and a side thereof are provided with supporting feetto enable the machine to be supported in either position of the base, ofstructure including a member projecting from the base, and an armcarried at the outer end portion of said member and angularly movablethereon, said arm being provided. with means which serves as asupporting foot for the machine when the latter is positioned to besupported by the feet at the side of 5 the base.
